How do I send SMSes from Salesforce?

What would be the approach to create an SMS application (either in Salesforce or other language) to send SMS from Salesforce? Is it feasbile if the client-side process is done through a streaming API (from the client side)?


A number of companies provide SMS services that you pre-pay for and invoke using a REST API. To send an SMS is usually quite simple e.g.:

private static final String ENDPOINT = '';
private static final String VERSION = '2010-04-01';

public void send(String toNumber, String message) {

    // Custom setting containing SMS service information
    SmsConfiguration__c config = SmsConfiguration__c.getInstance();

    HttpRequest req = new HttpRequest();
    req.setHeader('X-Twilio-Client', 'salesforce-' + VERSION);
    req.setHeader('User-Agent', 'twilio-salesforce-' + VERSION);
    req.setHeader('Accept', 'application/json');
    req.setHeader('Authorization', 'Basic '+ EncodingUtil.base64Encode(Blob.valueOf(
            config.AccountSid__c + ':' + config.AuthToken__c)));
    req.setEndpoint(ENDPOINT + '/' + VERSION + '/Accounts/' + config.AccountSid__c
            + '/SMS/Messages');
           + 'From=' + EncodingUtil.urlEncode(config.FromNumber__c, 'UTF-8')
           + '&To=' + EncodingUtil.urlEncode(toNumber, 'UTF-8')
           + '&Body=' + + EncodingUtil.urlEncode(message, 'UTF-8')
    HttpResponse res = new Http().send(req);
    if (res.getStatusCode() >= 200 && res.getStatusCode() < 300) {
        // OK
    } else {
        // Error

You could expose your own simple @RestResource endpoint that you call from the client side to in turn call the above code on the server:

global with sharing class SmsRest {
    global static void doPost(String toNumber, String message) {
        new SmsSender().send(toNumber, message);

or that could say accept the ID of the Contact to send to and query to get the number and then send.
